DebriefBot v1.0.2 - Debrief Permalinks

• Updated the debrief flow to account for more scenarios (e.g. unrecognised commands like /debrief asdosadksds 🤔)
• DebriefBot now posts a message with permalinks when updating an existing debrief (no more scrolling up to find it! 🎉)
• Refactored and cleaned up code 🛀🏾 to remove unnecessary variables, commented-out lines, redundant steps, nested code, etc.
• Added in environment-driven token selection and dev/prod run commands in package.json to make testing easier. It is now easier to switch between prod and test Slack workspaces without having to switch tokens, change code or modify Slack App platform config
